This is Dr. David
I am a cancer doctor.
I am sorry about your friend who has cancer of the tongue.
surgery in the neck can often cause scar tissue which can be very hard and stiff.
scar tissue is always harder and stiffer than our regular tissues.
once she is healed up from her surgery, she needs to try to stretch her neck and scar tissue as much as she can.
the best time to stretch scar tissue as soon as possible after the surgery.
radiation therapy can also cause scar tissue of the neck and stiffness, so she needs to begin stretching now to help soften up the scar tissue as soon as possible and continue to stretch during the radiation.
she can see a physical therapist to help guide her in how she can stretch her neck.
I tell patients of mine to stretch the neck in 6 directions for 20-30 seconds in each directly 4-8 times a day
chin down to chest, chin up to sky are two directions
chin over shoulder left and right are two more
and ear to shoulder left and right are two more ways to stretch.
